Description

Technical Field

[0001] This utility model relates to the field of razor technology, and in particular to a flip-top razor head and a manual razor. Background Technology

[0002] Traditional manual razors typically consist of a blade holder and a cap. The cap has a connecting post that passes through the blade holder and screws onto the razor handle. To install the blade, first rotate the handle to separate the handle, blade holder, and cap. Place the blade flat on the blade holder, then place the cap on top, allowing the stud to pass through the blade and blade holder. Finally, screw the handle onto the stud and tighten it, thus holding the blade in place between the cap and the blade holder. This type of manual razor usually only has one blade installed between the cap and the blade holder. The cap has a stud that passes through the blade holder and screws onto the razor handle. The blade installation and removal in this type of manual razor is relatively cumbersome. Furthermore, it typically only accommodates one double-edged blade, resulting in lower shaving efficiency.

[0029] Reference Figures 1 to 4 According to a first aspect of the present invention, a flip-top blade includes a blade holder 100, a middle cover 200, and a top cover 300. One side of the blade holder 100 is provided with a first mounting position 110 for placing a first blade. The blade holder 100 has a first end 100a and a second end 100b, and the first mounting position 110 is located between the first end 100a and the second end 100b. One end of the middle cover 200 is rotatably mounted to the first end 100a. The first mounting position 110 is located between the middle cover 200 and the blade holder 100. A [missing information - likely a design element] is provided on the side of the middle cover 200 facing away from the first mounting position 110. The second mounting position 210 is used to place the second blade. The middle cover 200 and the blade holder 100 are used to clamp and fix the first blade together. One end of the top cover 300 is rotatably mounted on the first end 100a, and the other end of the top cover 300 is located on the side of the middle cover 200 away from the first mounting position 110. The top cover 300 and the middle cover 200 are used to clamp and fix the second blade together. A positioning device is provided between the top cover 300 and the blade holder 100. When the other end of the top cover 300 rotates and approaches the second end 100b, the positioning device can unlockably lock the top cover 300 to the blade holder 100.

[0030] Reference Figure 1 and Figure 3 The flip-top cutter head provided by this utility model allows for the installation of a first blade at the first mounting position 110 on the cutter holder 100 and a second blade at the second mounting position 210 on the middle cover 200 after the top cover 300 is opened. When the other end of the top cover 300 is rotated to approach the second end 100b of the cutter holder 100, the positioning device restricts the position of the top cover 300, keeping it closed. At this time, the top cover 300 and the middle cover 200 can clamp and fix the second blade, and the middle cover 200 and the cutter holder 100 can clamp and fix the first blade. Therefore, the flip-top cutter head provided by this utility model can install the first blade. The second blade is provided to improve shaving efficiency. When the blade needs to be removed from the flip-top shaving head, the locking action formed between the positioning device and the blade holder 100 is unlocked, and the second end 100b of the top cover 300 away from the blade holder 100 can be flipped to open the top cover 300. At this time, the top cover 300 and the middle cover 200 no longer hold the second blade, and the middle cover 200 and the blade holder 100 no longer hold the first blade. Thus, the first blade and the second blade can be removed. With the above settings, the flip-top shaving head provided by this utility model can remove and install the blades simply by opening or closing the top cover 300. Removing and installing the blades is convenient and simple.

[0031] In specific implementation, the first blade can be a single-edged blade or a double-edged blade, and the second blade can also be a single-edged blade or a double-edged blade. Since blades are common components in this field, the first and second blades are not shown in the accompanying drawings, and their specific structures and forms will not be described in detail here.

[0032] In some embodiments, after the blades are installed, one cutting edge of the first blade and one cutting edge of the second blade are close to the second end 100b of the blade holder 100, thereby allowing shaving to be performed from the second end 100b of the blade holder 100.

[0033] Of course, in other embodiments, there is a gap between one end of the middle cover 200 and the first end 100a of the blade holder 100 to expose the blade of the first blade, and there is also a gap between the end of the top cover 300 near the first end 100a of the blade holder 100 and the middle cover 200 to expose the blade of the second blade, so that shaving can be performed from the first end 100a of the blade holder 100.

[0034] Reference Figures 1 to 3According to some embodiments of the present invention, the top cover 300 has a baffle 310, which is located on one side of the second end 100b. The positioning device includes a ball bearing 400, which is installed on the cutter holder 100 and the baffle 310 has a positioning hole 320 for the ball bearing 400 to be engaged. Alternatively, the ball bearing 400 is installed on the baffle 310 and the cutter holder 100 has a positioning hole 320 for the ball bearing 400 to be engaged. The ball bearing 400 can automatically extend or retract, or the baffle 310 is elastic. With the above settings, when the top cover 300 needs to be closed, the user only needs to exert a certain amount of force to rotate the other end of the top cover 300 toward the second end 100b of the tool holder 100. Through the automatic extension and retraction of the ball bearing 400 or the elastic deformation of the baffle 310, the ball bearing 400 will be locked in the positioning hole 320. When the top cover 300 needs to be opened, the user only needs to exert a certain amount of force to rotate the other end of the top cover 300 away from the second end 100b of the tool holder 100. Through the automatic extension and retraction of the ball bearing 400 or the elastic deformation of the baffle 310, the ball bearing 400 will be disengaged from the positioning hole 320. This releases the locking effect of the positioning device between the top cover 300 and the tool holder 100, allowing the top cover 300 to be opened.

[0035] The portion of the ball 400 used for insertion into the positioning hole 320 is spherical or hemispherical. The ball 400 can be made entirely of elastic material, or the ball 400 can be configured as an elastic top bead structure.

[0036] Reference Figures 1 to 3 In the specific implementation process, the top cover 300 is provided with two baffles 310, and the second end 100b of the razor holder 100 is located between the two baffles 310. Each baffle 310 has a positioning hole 320, and the second end 100b of the razor holder 100 is correspondingly equipped with two ball bearings 400. Thus, after the top cover 300 is closed, the two ball bearings 400 are locked into the two positioning holes 320. Through the function of the positioning device, the position of the top cover 300 in the closed state can be locked, preventing the top cover 300 from shaking violently during user use of the razor.

[0037] In other embodiments, the positioning device described above may also be configured in other ways. For example, in some embodiments, the positioning device may include two magnets that cooperate and attract each other, and the two magnets are installed one-to-one on the blade holder 100 and the baffle 310. In other embodiments, the positioning device may also include Velcro, and the female and male parts of the Velcro are installed one-to-one on the blade holder 100 and the baffle 310.

[0038] Reference Figure 1 and Figure 2According to some embodiments of this utility model, the first mounting position 110 is provided with a first adsorption structure, which can be used to adsorb the first blade. During the blade installation process, the first blade is first placed in the first mounting position 110, and then the first blade is initially fixed by the adsorption effect of the first adsorption structure, thereby preventing the first blade from shifting position during the installation of the second blade, thus ensuring accurate blade installation; when removing the blade, during the opening of the top cover 300, the first blade will not be blown away by the adsorption effect of the first adsorption structure, avoiding accidents.

[0039] In some embodiments, the first adsorption structure may be configured as a first magnet 510; of course, in other embodiments, the first adsorption structure may also be configured as Velcro or other components capable of adhering to the blade.

[0040] Reference Figure 1 and Figure 2 According to some embodiments of this utility model, the middle cover 200 is provided with a second adsorption structure, which is located near the first end 100a. The second adsorption structure can be used to adsorb the second blade. Thus, during the blade installation process, the second blade is placed in the second mounting position 210, and then the adsorption effect of the second adsorption structure initially fixes the second blade, thereby preventing the second blade from shifting position during the process of closing the top cover 300, thus ensuring accurate blade installation. When disassembling the blade, during the process of opening the top cover 300, the second blade will not be blown away by the adsorption effect of the second adsorption structure, avoiding accidents.

[0041] In some embodiments, the second adsorption structure can be configured as a second magnet 520; of course, in other embodiments, the second adsorption structure can also be configured as Velcro or other components capable of adhering to the blade.

[0042] Reference Figure 4 In the specific implementation process, the main body of the middle cover 200 is a relatively thin plate. The middle cover 200 does not have enough thickness to install the second magnet 520. Therefore, the middle cover 200 is provided with a second mounting part 230 protruding towards the tool holder 100. The second magnet 520 is installed in the second mounting part 230. The tool holder 100 is provided with a relief groove 140 for avoiding the second mounting part 230.

[0043] In practical implementation, the top cover 300 and the middle cover 200 can be made of plastic or metal. When the middle cover 200 is made of magnetic metal, the first magnet 510 can also attract it. Specifically, during blade installation, the first blade is placed in the first mounting position 110, and then the middle cover 200 is rotated to cover the first blade. Under the attraction of the first magnet 510, the middle cover 200 can initially press the first blade onto the blade holder 100, thus initially fixing the first blade. When the top cover 300 is made of magnetic metal, the second magnet 520 can also attract it, thereby increasing the damping that confines the top cover 300 to the closed state.

[0044] Reference Figure 1 and Figure 2 According to some embodiments of this utility model, a rotating shaft 120 is provided at the first end 100a of the blade holder 100. The first end 100a is pivotally connected to one end of the middle cover 200 and one end of the top cover 300 via the rotating shaft 120. Thus, the top cover 300 can rotate around the rotating shaft 120, and the middle cover 200 can also rotate around the rotating shaft 120. With the above arrangement, the top cover 300 and the middle cover 200 are coaxially mounted on the first end 100a of the blade holder 100. In this way, the installation of the top cover 300 and the middle cover 200 is more convenient, and the structure of the entire flip-top blade head is simpler.

[0045] Reference Figure 1 and Figure 4 According to some embodiments of this utility model, the second end 100b is provided with a lubricating element 600, which is used to lubricate the skin during the user's use of the razor to improve the user experience.

[0046] Reference Figure 1 and Figure 2 In the specific implementation process, the second end 100b protrudes in the direction away from the first end 100a and is provided with two first mounting parts 130. The lubricating component 600 is a lubricating column, which is rotatably installed between the two first mounting parts 130.

[0047] Reference Figure 1 and Figure 2 According to some embodiments of this utility model, a protruding post 220 is provided on the middle cover 200, and an insertion hole 330 is provided on the top cover 300. When the other end of the top cover 300 rotates and approaches the second end 100b, the protruding post 220 is inserted into the insertion hole 330. The protruding post 220 can be used to position the second blade, or it can also be used to cooperate with the side wall of the insertion hole 330 to reduce the degree of relative shaking between the middle cover 200 and the top cover 300 during user use of the razor.

[0048] Reference Figure 1 and Figure 2According to some embodiments of the present invention, the top cover 300 has two opposing baffles 310. When the other end of the top cover 300 rotates and approaches the second end 100b, the middle cover 200 and the blade holder 100 are located between the two baffles 310. Thus, the baffles 310 can be used to cover the non-blade edges of the first blade and the second blade, which can play a protective role. Moreover, the middle cover 200 and the blade holder 100 are at least partially hidden inside the top cover 300, making the entire flip-top blade head more aesthetically pleasing.

[0049] Reference Figure 1 and Figure 2 According to some embodiments of the present invention, the baffle 310 is provided with an operating part 311, which is used to operate the top cover 300 to rotate. Thus, the operating part 311 can provide the user with a force application position to operate the top cover 300 to rotate, thereby making it convenient for the user to rotate and open the top cover 300 and avoiding slippage when opening the top cover 300.

[0050] According to a second aspect of the present invention, a manual razor includes the aforementioned flip-top blade head. By employing the aforementioned flip-top blade head, the manual razor can simultaneously install both a first blade and a second blade to improve shaving efficiency, and also ensures that blade installation and removal are simple and convenient.

[0051] Manual razors typically also include a handle, which is connected to the razor holder 100.

[0052] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
